Y0U Asked: if it is worthwhile changing to the longer extended wings Look at Richard Shirley's on KRNet.org. Build it like that and you will have more fun than anyone deserves to have on this planet. He used a different wing, but it is much shorter. Don't know what the airfoil designation is, but there are others on the net who do.
YOU Asked: hinges are made of about .9mm stainless plate bent into "U" shapes I suppose that you can go any route that you like, but I would use extruded aluminum, full length hinges for the ailerons and the Dr. Dean hinges for the tail surface hinges.
